title: The effect of fecal turbidity on norovirus detection by reverse transcriptase polymerase chain reaction.
abstract: A 10-min fecal preparation results in greater specimen turbidity than a 45-min protocol, but reverse transcriptase polymerase chain reaction (RT-PCR) norovirus test sensitivity is essentially the same. Feces processed so that particle size does not exceed approximately 560 nm do not display greater norovirus RT-PCR inhibitory effects than those that have undergone greater purification.
